Polk County’s Land Development Code is already one of the more ADU-friendly in Central Florida. The county permits “accessory living quarters” in most residential zones, allows both detached and attached configurations, and does not prohibit independent kitchens. That makes Polk a comparatively forgiving county for ADU projects today, under current code.

Florida’s 2026 ADU preemption bill (SB 48) did not become law, so any further change (including removing owner-occupancy on larger parcels) would now come through the county’s own ordinance process rather than state mandate. See the Florida ADU law pillar (or in Spanish) for the statewide legal picture and the SB 48 post-mortem for the legislative record.

Polk is the fastest-growing county in our coverage area by percentage, with the Lakeland–Haines City–Davenport corridor absorbing significant population from both Orlando and Tampa commuters. ADUs here are a practical middle-housing response and are supported by county leadership in public comments.

Incorporated cities in Polk County with their own ADU rules:

  • Lakeland ADU Rules (2026): Polk County’s largest city; ADUs require compatibility review by the Planning and Zoning Board (not administrative); Urban area geographic gate applies; transportation impact fees exempt (~$754 total); kitchens and owner-occupancy require direct confirmation with Planning

Permit throughput

Polk’s Planning & Development office processes ADU applications in 8–14 weeks on average, which is the fastest in our coverage area. Fees are also among the lowest, at $1,500–$2,800 total for a 600 sq ft ADU including impact fees. Combined with the relatively low land and construction costs in Polk compared to Orange or Seminole, this makes Polk one of the better-penciling counties for ADU projects intended as long-term rental income.
